Comparing the effectiveness of dietitian delivered nutrition education either as a single intensive session or five short sessions for people with prediabetes
Prediabetes is a worldwide growing epidemic and a key risk factor for progression onto type 2 diabetes. Interventions targeting prediabetes are required to delay or prevent the onset of diabetes. A pilot study was undertaken involving 11 participants with prediabetes. The participants were randomly assigned to either a single session or multi session (five sessions) dietary education intervention conducted by a single dietitian with an overall contact time of 60 minutes. Outcome measurements were collected in the form of HbA1c, weight, blood lipids and nutrition knowledge score. No significant differences were found between the intervention groups in either metabolic outcomes or nutrition knowledge. The analysis of the small sample size should be interpreted with caution and is for interest purposes only. The small sample size may have contributed to the lack of statistically significant results and a larger sample size would be recommended. Few studies have compared similar methodology of consistent contact time over single or multiple sessions. Further programmes could incorporate a longer contact time which could be used to integrate more behaviour change techniques and individual goal setting which may result in greater improvement in measurements.
